Fabric and method of making the same



Patented 1931 UNITED STATES PATENT OFFICE JOSEPH C. FARBER, OF CLEVELAND HEIGHTS, OHIO, ASSIGNOR TO THE FRIEDMAN- BLAU-FARBER COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO FABRIC AND METHOD OF MAKING THE SAME No Drawing.

The present invention relates to a process for manufacturing a knitted fabric having a roughened or creped appearance and particularly adapted to be used as a material a for outer garments such as sweaters, coats,

dresses, caps, etc.

The general object and nature of my invention is to produce such a fabric by a simple and economical process which does no not possess the disadvantages and costly operations existent in the prior art. ore precisely, the principle of my invention involves the method of first knitting or weaving a fabric composed of yarns or threads having variable shrinkage properties, and then subjecting the resultant fabric to a shrinking operation whereby the strands or yarns possessing the lower coeflicient of shrinkage will be forced out to the exterior portion of the fabric in order to roduce a crinkled or creped appearance. uch processes have heretofore been accomplished by means of shrinking agents such as acids or absorbents. An object, therefore, of the instant invention is to produce a rough textured fabric by means of a process wherein the obvious disadvantages incident to the use of expensive shrinking reagents are not pres ent.

-A further object is to produce a fabric from materials which are most particularly adapted to react to the operations of my process. To the accomplishment of the foregoing and related ends, said invention, then, as consists of the means hereinafter fully described and particularly pointed out in the claims. The following description sets forth in detail one method and one product exemplifying my invention, such disclosed W procedure and product constituting, however, but one of various applications of the principles of my invention.

The first step of m process contemplates the production of a fa r1c consisting of yarns 5 of animal fibre and artificial fibre. More Application filed June'3, 1931. Serial No. 54.1,955.

particularly I contemplate the use of wool and rayon yarns, respectively. The tWo yarns are knitted together in an ordinary Jersey stitch in the form of double strands. The resultant knitted fabric is then subjected to an ordinary soap and water shrinking process which has the result of substantially contracting the wool yarns and forcing the comparatively non-shrinkable rayon yarns into crinkled loops, giving a roughened or woolly appearance to the completed fabric. Where an ordinary knitting stitch is primanly employed, the loops of rayon yarn will be forced out on both surfaces of the fabric. It is'possible, however, by means of using a plaited stitch to produce a final result whereby the crinkled rayon loops appear only on one side of the fabric. Like- Wise, the initial utilization of a pattern stitch will produce an ultimate fabric having the crinkled rayon effect appearing in areas in conformity to the preliminary pattern.

Qther modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the roduct and method herein disclosed, provlded the step or steps stated by any of the following claims or the equivalent of such stated step or steps be employed.

I therefore particularly point out and distinctly claim as my invention:

1. In the method of producing crepe like effects on fabrics, the steps which consist in twisting together yarns of rayon fibre and Wool fibre to form a double strand, forming a fabric from such strands and then shrink ing one yarn to the extent that the other yarn is looped.

2. In the. method of producing crepe like effects on fabrics, the steps which consist in twisting together yarns of rayon fibre and wool fibre to form a double strand, forming a fabric from such strands, subjecting said fabric to a shrinking solution, said solution being of such a character as to affect only said yarns of wool fibre.

3. A fabric having a crepe like appearance comprising yarns of animal fibre and arti- 6 ficial fibre twisted together, said animal fibre yarns being shrunk, and said artificial fibre yarns forming crinkled loops on the exterior of said fabric.

4. A knitted fabric comprisin yarns of 10 wool fibre and rayon fibre twiste together, said Wool fibre yarns being shrunk and said rayon fibre yarns forming crinkled loops on the exterior of said fabric.

Signed by me, this 1st day of June, 1931. JOSEPH C. FARBER.
